ADP1706ACPZ-1.0-R7

ADP1706ACPZ-1.0-R7 is a linear voltage regulator from Texas Instruments. It is a low dropout, low quiescent current, high PSRR linear voltage regulator which is designed to provide adjustable output voltage from 1.0V to 6.5V for a maximum output current of 600mA.

This linear voltage regulator features a thermal limiting circuit which is designed to protect the device from overheating by reducing the output current when the junction temperature exceeds a certain limit. Its ESD protection level rating is HBM 2KV, which makes it suitable for use in industrial and automotive applications. This voltage regulator also includes a shutdown pin, which can be used to shut down the device to reduce overall power consumption.

Application Fields

ADP1706ACPZ-1.0-R7 is suitable for use applications such as telecommunications, automotive and other industrial controls, as well as consumer electronics such as laptops, cellular phones and portable media players. It is designed to provide a low voltage regulated power supply for processor cores and other low voltage system components where high efficiency, low dropout and low output ripple are desired.

The low dropout voltage of this linear voltage regulator makes it suitable for use in applications where the input voltage may vary over a wide range. It is also suitable for use in applications where the input voltage is not well regulated, as the low quiescent current reduces power consumption even if the input voltage fluctuates. Furthermore, its high PSRR ensures minimal noise present in the output.

Working Principle

The ADP1706ACPZ-1.0-R7 is a type of linear voltage regulator, which works by using a linear pass transistor to regulate the output voltage. The regulator compares the input voltage to a reference voltage, and then regulates the output voltage by controlling the conduction of the linear pass transistor.

The regulator\'s reference voltage is determined by an internal voltage divider connected to an internal reference voltage. The output voltage is set by connecting a resistive divider to the output pin, and the output voltage is adjusted by varying the values of the resistors in the divider. The regulator also includes an error amplifier which is used to compare the output voltage to the reference voltage. Once the two voltages match, the linear pass transistor is then used to regulate the output voltage.

The thermal limiting circuit included in the voltage regulator is designed to protect the device from overheating, and works by detecting the junction temperature of the device. When the junction temperature reaches a certain limit, the output current is reduced to prevent the device from overloading and damaging itself.
